Abstract: Abuse-resistant therapeutic pharmaceutical formulations include a cationic drug and at least one anionic polymer. Particular arrangements of the cationic drug and the at least one anionic polymer prevent the cationic drug from being extracted from the formulations in solvents and conditions commonly used by drug abusers attempting to isolate the cationic drug from its formulation.

Abstract: A form stable gel may be used to make a seal between substrates to minimize air and moisture penetration. The form stable gel is useful in construction industry applications such as sealing window frame members, sealing retrofit and replacement windows, as well as indoor applications such as sealing bathtubs, sinks and shower surrounds. The form stable gel is also useful for sealing applications in boat hulls.
